1995Bl06: produced by projectile fragmentation of 78Kr at E=73 MeV/nucleon (Ni(78Kr,X)) at SISI/LISE facility at GANIL. 70Kr was identified using tof and ΔE-E.
2000Oi02: produced by 1 GeV proton-induced spallation in a Nb foil (Nb(p,X)) at Cern. Isotopes separated using ISOLDE. α plastic scintillator, a HPGe detector (as a β telescope) and a gas-Si detector (to detect the β-delayed protons) were used. Measured T1/2 using the time correlation between the proton pulse and β(t). Subset of results presented in 2002Oi02.
2002Bl17: produced by fragmentation of 78Kr beam (9Be(78Kr,X)) at E=73MeV/nucleon at GANIL. Separated using LISE3 and identified through ΔE and tof measurements. α silicon telescope was used. Measured T1/2 from time correlation between ion implantation and β events in the silicon strip detector.
2014Ro14: produced by fragmentation of a 78Kr beam on a natural Ni target with E(78Kr)=70 MeV/nucleon. Separated using the LISE3 spectrometer and identified using ΔE-tof measurements. α silicon telescope was used. Measured T1/2 from time correlation between ion implantation and β events in the silicon strip detector.
